BENJAMIN FgLEET, OF DAYTON, NEVADA.

Letters Patent-No. 96,449, dated November 2, 1869.

To all whomt't may concern:

Be it known that I, BnNJAntx F. LEET, of Dayton, in the county of Lyon, :unl Sta-te ot' Nevada, have .invented a new and improved Compound Wheel and Axle; and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled .in the art to nia-ke and use the same, reference being had to the accompanying drawings, forming part otl this specilication.

lhis invention rela-tes to new and useful improvements in wheels and axles for railroad-cars, whereby it is designed to provide a sim ple and strong arrangement ot' imlependently-revolvng wheels, calculated also to utilize the wheels and axles now in use hy removing one of the tixed wheels and substituting a. loose wheel, aeeording to my improvement, which consists iu the application to the common railrozul-.earaxle, having a solid collar shrunk on at the centre, of wheels hawing a hollow stem prtjeeting from the inner faces to the said collars, and held in place by loose sleeves, made in two partshaving internal lianges,

which engage behind shoulders of .projecting rims en the inner ends of the stents, and hold theln against tlnl ends ofthe Collars shrunk on the axles.

These loose wheels are provided with friction-rollers at the outer and inner bearings, and the stems ofthe wheels, and the loose sleeves which hold them on the axles, are provided with oil-clnunbers, having capacity for large supplies of oil.

Figure 1 is a lmigitudinal section through the axle and wheels.

Figure 2 is a transverse section, through the loose sleeveand axle, on the line :v a: ol iig. 1.

Similar letters ot' reference indicate corresponding parts.

B is the axle, and A, a fixed -wheel thereon, of the common arrangement. l

'lo the opposite end of the axle, I apply a loose wllell, having a hollow ste-in, l), extending to or nearly to the centre ot' the axle, and bearing' at the iuner'end (which is casi or formed with a shoulder and projection, 15,) against a strong collar, l", shrunk on the axle.

This stein is bored out at each end, for the reception ot' ii'iction-rolleis G, for bearing upon the axle,

and it is held against the end ot' the collar F to'preventi-end motion by a loose sleeve, H, made in two parts, and having internal flanges, I K, taking against the shoulders at the outer end ot' the shoulders and projections E andcolln F.

The said sleeve H is provided with lugs, L, through which bolts pass for screwing the lugs together, to hold the sleeve in place on the axle.

Both this sleeve H and the stem D of the wheel are chamhered, as at N O, to provide oil-chambers, into which the oil may be poured through small holes, closed by screwplngs P l.

I propose also, when required, to place two of these loose wheels C, with stems on the axle holding them against the collar l1`,in the saine way by the sleeve H, thereby providing. for each wheel to 'revolve independently of the other and of the axle.

It will be seen that hy this arrangement the axle is greatly strengthened 'hy the support aiflnded by the collar P, and the extensions ol" the wheels, removing the objections existing to the axles divided at the centre.

The friction-rollers G may lie dfspensed with, if pre ferred, and I propose to use them or not, as found best.

Itv will be observed that by this arrangement of two loose wheels on the shaft, the tendency ot' the journals' to heat willbe very much reduced, if notwholly prevented, for if the axle journals become dry, the axle will cease to revolve, and the wheels will run on it, or it' the bearings of the wheel becomedry, the axles all turn in their bearings.

It will also be observed that the hearing-surfaces of the loose wheels are at the under side, whereby they will be more effectively lubricated.

Having thus descrihed my invention,

I elahn as new, and desire to secure by Letters Pater|t The combination, with the axle 1S and wheel A, permanently connected thereto, ofthe loose wheel U, and stem, collar l", and sleeve H, the stem l) or wheel being either provided with tiiotion-rollers or Ilot, all substantially as specified.

The ahove'specitieation of my invention signed by me, this 16th day of September, 1869.
